To protect you from the climate – and protect the climate from you. We make shoes that bring performance qualities into everyday life: waterproof, temperature-regulating, and built to last. We think about the weather, so you don’t have to.
From the moment we were born, we were taught how to deal with the harsh Nordic weather conditions. And as a result, we welcomed it! We learned to embrace the outdoors with open arms, regardless of the weather. This is how we were raised, and this is how Kastel Shoes was born.

Sustainability is complex. Just like 30% less sugar isn’t sugar-free, we don’t just claim to be sustainable. We take action!
Our approach involves bold experiments in materials, design, and business models across three phases. Viable ideas become pilot products, and successful pilots set new standards and innovations.
Sustainability in Kastel shoes thrives on aligned, ongoing efforts.
In our Nature Lab, we explore new ways to make shoes that perform better, last longer, and leave a smaller footprint. Here are some of the materials and concepts that have made it from lab to street.
Inspired by fishermen. Built to last. Waterproof membranes work—until they don’t. One small tear can ruin them. That’s why we use tough PU, like the raincoats fishermen wear. The result: shoes that last longer and handle real weather.
Norwegian wool. Naturally prepared for weather. Wool is strong, breathable, and water-resistant by nature — just like the animals it comes from. We use Norwegian wool to stay close to our roots and reduce unnecessary transport. A smart material for shoes built for the outdoors.
3D-knitted wool. Light, breathable, and easy to care for. Wool keeps your feet cool, fresh, and dry — no synthetic treatments needed. The 3D-knit construction adds airflow, reduces waste, and gives a flexible fit. And when it needs a refresh? Just toss it in the wash.
Less parts. Less waste. Same performance. We’ve made it standard to reduce the number of components in every new Kastel shoe. Smarter design means less waste — without compromising on function or durability. Since 2019, every style has been built this way.
Smarter sizing. Less waste. Instead of making half sizes, we created a size insert that adjusts the fit. It reduces overproduction, returns, and complexity.
Hemp treated for weather. Naturally strong. We’re exploring hemp as a low-impact alternative to polyester. It's strong, breathable, and grows with less water than cotton. By treating it with natural waxes, we’ve added water resistance — without the use of harsh chemicals.
Why aren't there shoes made for Norwegian weather? From that moment, we’ve followed our curiosity — learning, testing, and building one step at a time. Here's how Kastel came to be, and where we're heading next.
Inspired by the skate-shoe culture of the 90s, 13-year-old Andreas Malo Dyb decides he’ll one day start a Norwegian sneaker brand.
Andreas studies Industrial Design in Milan before returning to Norway to work at Dale Skofabrikk — where he learns classic shoe craftsmanship from the ground up.
Andreas gains hands-on experience working with Norwegian outdoor footwear brands, building knowledge in weather-specific performance.
Seventeen years after the dream began, Kastel was born — offering clean sneakers designed for Nordic weather.
Kastel releases its first summer shoe with an elastic heel. Easy to slip on, easy to love.
Madla is launched — a waterproof sneaker/boot hybrid that challenges the market. No more soggy shoes or stiff boots.
Kastel launches its first Merino wool sneaker, exploring natural materials for warmth, breathability, and comfort.
Kastel’s first shoe using local Norwegian wool from the endangered Grå Trønder sheep — strong, breathable, and naturally weather-ready.
A new chapter: Kastel develops its first membrane-free waterproof shoe. Lightweight, flexible, and chemical-free.
Stavern is designed with just 11 components instead of 31 — lighter, stronger, and machine washable. A step toward smarter, cleaner design.
Madla gets a hemp update — durable, breathable, and waterproofed with beeswax for longer life and fewer synthetics.
To avoid overproduction, Kastel creates a white wool sneaker that can be dyed to any color — every shoe has the potential to be the bestseller.
Kastel develops its first working prototype of a 3D-knitted sneaker made from Norwegian wool. Locally produced, minimal waste, and full of future potential.
Kampen introduces Kastel’s modular system: interchangeable details that let you upgrade and refresh your shoes instead of replacing them.
